Abstract
A solar water heater capable of focusing light and multilayer heat insulation comprises using metal pipes with length of 180 centimeters and diameter of 12 centimeters, coating heat absorption films on the surfaces to lead the metal pipes to be both heat collecting pipes and water storage pipes, the metal pipes are coated by transparent vacuum glass heat-insulation pipes, keeping an seven-millimeter air heat-insulation layer between the heat-insulation pipe and the heat collecting water storage pipe, then coating a big diameter glass outer pipe on the glass heat-insulation pipe, coating a reflecting film on downsun surface of the pipe outer pipe to lead a surface facing inward to be a mirror plane as a solar cooker, reflecting and focusing light on mirror plane of the outer pipe to the heat collecting water storage pipe to elevate water temperature, leading the heat collecting water storage pipe to have three insulation layers of air-vacuum-air, and finally connecting the heat collecting water storage pipe to a water inlet pipe and a water outlet pipe to form a water heater unit. A water outlet pipe of the upper unit is connected with a water inlet pipe of the lower unit, a plurality of units can be communicated and disposed in parallel for civil use, and groups of units can be communicated and installed for industrial heating. The solar water heater has wide usage area and simple installment, which is practical and beautiful.
Description
Technical field
The present invention relates to a kind of solar water heater, relate in particular to the solar water heater of a kind of sunlight focusing, multi-layer heat preserving.
Background technology
Present known solar water heater, major part is that sunlight directly shines formula, can not sunlight be focused on as solar cooker, the amount of heat of instant heating hydrophone thermal-collecting tube gained directly depends on the size of its light-receiving area and the power of illumination, use in the area that illumination is more weak, it is little to get heat, the intensification weak effect, glass heat collection tube is the individual layer vacuum heat-preserving in addition, and heat insulating ability is poor.
Summary of the invention
For the limitation that overcomes present thermal-collecting tube of solar water heater light-receiving area and the problem of heat insulating ability difference, the invention provides the solar water heater of a kind of sunlight focusing, multi-layer heat preserving.
Solve its technical problem, the technical solution used in the present invention is: utilize the principle of solar cooker, sunlight focused on, the quantity of illumination of the thermal-collecting tube that is multiplied, thus improve thermal-collecting tube heat.Be with about 12 centimetres of diameters, the metal tube that length is about 180 centimetres, appearance is handled through the absorption film coating, and making it is thermal-collecting tube, is again water pipe; Claim the collector metal water pipe, radially overlap a transparent vacuum glass heat-insulating pipe in the tube outside, insulating tube internal layer diameter and length form the space all above collector metal water pipe 7 millimeter, become one deck gas heat-insulation layer; Radially overlap a clear glass outer tube at outermost layer, the opaco of glass outer tube is coated with reflectorized materials such as mercury, makes its one side inwardly become minute surface; Make collector metal water pipe, vacuum heat-preserving tube, glass outer tube place the concentric position with fastener; Sunlight shines the minute surface of outer tube, and minute surface focuses on the collector metal water pipe with sunlight, promotes the temperature of water pipe, and according to the diameter of the power of the requirement of water pipe temperature and local illumination being set the glass outer tube, temperature required height then increases bore outer pipe, otherwise then little; Air in the glass outer tube and vacuum glass heat-insulating pipe are become low heat conductivity gas bodies such as carbon dioxide with air displacement in the thermal-arrest water pipe gap, make the collector metal water pipe that gas-vacuum-three layers of insulation of gas be arranged; Sealing of collector metal water pipe, other end insert inlet tube and outlet tube, and water inlet pipe stretches into the water pipe bottom always, and this has just become a water heater unit, and the outlet pipe of last unit is connect the water inlet pipe of lower unit, can install side by side a plurality of unit, but also group install.Outside inclined roof, flat-top, high building wall, all can install easily as long as can shine the place of sunlight, attractive in appearance, practical.
The invention has the beneficial effects as follows that big, the quick heating of heat-collecting capacity can be civilian, also can industrial heat-obtaining usefulness, easy for installation, all pressure bearing type.
Description of drawings
Below in conjunction with accompanying drawing the present invention is further described.
Fig. 1 is the solar water heater schematic diagram of sunlight focusing of the present invention, multi-layer heat preserving.
1. built on stilts fastener, 2. half two-way mirror outer tube, 3. vacuum glass heat-insulating pipe, 4. gas heat-insulation layer, 5. collector metal water pipes among the figure, 6. heat-barrier material block, 7. water inlet pipe and water outlet pipe, 8. in the glass block, 9. outer glass is blocked a shot, 10. heat insulation fastener, 11. outer tube minute surfaces, 12. clips, 13. rubber washers.
With about 180 centimetres of length, the metal tube that diameter is about 12 centimetres, stainless steel tube is proper, extexine carries out the absorption film coating to be handled, and making it is thermal-collecting tube (5), is again water pipe, and establish attemperater no longer in addition, its length, diameter can be set according to purposes; At collector metal water pipe overcoat transparent vacuum glass heat-insulating pipe (3), the radius of insulating tube internal layer and length surpass collector metal water pipe 7 millimeter is advisable, and makes its gap that becomes 7 millimeter, becomes one deck gas heat-insulation layer (4); Overlap a clear glass outer tube (2) at outermost, the opaco of glass outer tube is coated reflectorized materials such as mercury, makes its one side inwardly become minute surface (11), and the function of solar cooker is arranged; Make collector metal water pipe, vacuum heat-preserving tube, outer tube place same home position with the heat insulation fastener of built on stilts fastener (1) (10); Fastener between thermal-arrest water pipe and vacuum heat-preserving tube heatproof heat-barrier material is in order to avoid the nearly 100 degrees centigrade high temperature of thermal-arrest water pipe damages the vacuum glass heat-insulating pipe; Air displacement in the gap between air between glass outer tube and the vacuum glass heat-insulating pipe and vacuum glass heat-insulating pipe and the collector metal water pipe is become low heat conductivity gas bodies such as carbon dioxide, and it is better to make it effect of heat insulation; Sealing of collector metal water pipe, the heat insulation water inlet pipe and water outlet pipe (7) of heatproof is inserted in the other end, and water inlet pipe stretches into collector metal water pipe bottom always; Thermal-arrest water pipe, glass tube with vacuum and minute surface outer tube all cover hot top (6,8,9), and the hot top double as of collector metal water pipe and the heat insulation card of glass tube with vacuum fill up rubber ring (13) sealing between glass outer tube and the hot top, with clip (12) fastening; Hot top leaves the water inlet pipe and water outlet pipe preformed hole, waits to assemble the back and replaces into carbon dioxide by preformed hole, load onto water inlet pipe and water outlet pipe after, with foaming Ji sealing; Outside the minute surface of glass outer tube, fill up insulation cushions such as foamed plastics, just become a water heater unit; The outlet pipe of going up the unit can be inserted the water inlet pipe of lower unit pipe as required, a plurality of unit are communicated with installation side by side, also but group is communicated with installation, after the installation exposed water pipe insulation processing is got final product, this water heater is an all pressure bearing type, in inclined roof, flat-top, high building exterior wall, field, as long as there is the place of illumination to install easily.
